RAID: Level 1

RAID 1, referred to as mirroring, duplicates data across two or more disks, ensuring that each disk contains an identical copy.

This redundancy allows uninterrupted operation even if one disk fails, as the data remains accessible from the mirror.

Although read speeds may improve since multiple disks can be accessed simultaneously, write speeds are not significantly enhanced due to the need to write the same data to all disks.

Since half the total storage is reserved for redundancy, the usable capacity is effectively halved.

While this configuration offers excellent fault tolerance, it may not be cost-efficient for systems requiring high storage capacity.

RAID 1 is particularly suitable for applications where reliability is critical, such as transactional databases, backup systems, and small business servers. Moreover, its simplicity makes it an attractive choice for users who value ease of maintenance and data protection over performance optimization.
